Keyboard sound control (master volume)

[FONT= "Microsoft Sans Serif"]This is my first thread here and I will apologize if the section for this tread is on wrong place, correct me.

I have:
-Logitech Media Keyboard
-E-MU 1212m soundcard
-Windows 7 RTM 7600

I have problem with my media buttons on my keyboard, the volume buttons on my keyboard won't change the master volume from my sound card (E-MU 1212m) they change the Windows volume but not the SOUNDCARD volume. Before a year I didn't have that problem. I tried to rollback the drivers (even I made System Restore), I reinstalled the drivers, but the problem persist. I think that the problem is something with the Logitech driver priority for the keyboard but I dont know what to do after a year of searching.....

I will check this tread everyday just reply if you know something about this problem.

I will appreciate any help from you, thanks.[/FONT]
